Summary

Epilobium lamyi, commonly known as Lamy’s Willowherb, is a perennial herb native to Europe. This species typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). Lamy’s Willowherb has lance-shaped leaves and bears pink, showy flowers throughout the summer, which are particularly attractive to pollinators such as bees and butterflies.

Lamy’s Willowherb is valued for its ease of maintenance and the vibrant splash of color it adds to garden settings. It is commonly used in native plant gardens, borders, and as a component of pollinator-friendly landscapes. It thrives in full sun to part shade and prefers medium or fast-draining sandy or loamy soils. Gardeners should be aware that it can self-seed and spread if conditions are favorable, which may require management in smaller gardens.CC BY-SA 4.0
